As relações afetivas na prática tutorial e sua relação com a aprendizagem no curso a distância de licenciatura plena em química

In distance learning degree in Chemistry in full of the Secretária de Educação a distância da Universidade Federal do Rio Grande do Norte (SEDIS / UFRN). The teacher-tutor to establish the experimental subjects closer relationships with students, mediating the pedagogical actions that develop in the distance learning course, with a view to achieving the principles of autonomy and learning, contributing to the creation of learning environments collaborative, guided by affection.The article presents the results of an empirical research on affectivity in practice this tutorial experimental classes in higher distance education in the full degree course in Chemistry Polo Currais Novos/ RN, held between 2009 and 2010. The study is based on qualitative methodology, whose data were collected through questionnaires and semi-structured interviews with 48 (forty eight) students involved in distance learning courses and selected in order to compose a group of subjects who showed variability, as guidelines that guide the sampling procedures in qualitative research. The results, based on category theory and empirical analysis of data from the interviews were supplemented by information obtained from participant observation which also served to guide the data collection of the corpus of this work. With the results we understand that there is clarity about what characterizes a loving relationship between those involved in the process of teaching and learning in experimental classes in high school chemistry Distance Education. Furthermore, it was also clear that the communication process in dialogic teaching and learning in higher distance education in chemistry at the trial need to mark out in balanced affective attitudes, the experimental error that value and respect the many possible construction of knowledge by movements social interaction of individual and collective

Síntese e caracterização de poliacrilamidas modificadas para utilização na indústria do petróleo

Modified polyacrylamides with ≅ 0.2 mol % of N,N-dihexylacrylamide and hydrolysis degree from 0 to 25 % were synthesized by micellar copolymerization. The hydrophobic monomer was obtained by the reaction between acryloyl chloride and N,Ndihexylamine and characterized by infrared (IR) and proton nuclear magnetic resonance (1H NMR) spectroscopy. The polymer molecular structures were determined through 1H and 13C NMR spectroscopy and the polymers were studied in dilute and semi-dilute regimes by viscometry, rheometry, static light scattering and photon correlation spectroscopy, at the temperature range from 25 to 55 ºC. The data obtained by viscometry showed that the intrinsic viscosity from the hydrolyzed polymers is larger than the precursor polymers at the same ionic strength. The comparison between the charged polymers showed that the polymer with higher hydrolysis degree has a more compact structure in formation water (AFS). The increase of temperature led to an enhanced reduced viscosity to the polymers in Milli-Q water (AMQ), although, in brine, only the unhydrolyzed polymer had an increase in the reduced viscosity with the temperature, and the hydrolyzed derivatives had a decrease in the reduced viscosity. The static light scattering (SLS) analyses in salt solutions evidenced a decrease of weight-average molecular weight (⎯Mw) with the increase of the hydrolysis degree, due to the reduction of the thermodynamic interactions between polymer and solvent, which was evidenced by the decrease of the second virial coefficient (A2). The polymers showed more than one relaxation mode in solution, when analyzed by photon correlation spectroscopy, and these modes were attributed to isolated coils and aggregates of several sizes. The aggregation behavior depended strongly on the ionic strength, and also on the temperature, although in a lower extension. The polymers showed large aggregates in all studied conditions, however, their solutions did not displayed a good increase in water viscosity to be used in enhanced oil recovery (EOR) processes

Extensão universitária: concepções e ações na UFRN sob a temática direitos humanos e justiça no período 2008 a 2010

This paper concerns a study on the University Extension, by reference to the research extension activities under the theme human rights and justice, developed in the period 2008 to 2010 in UFRN. To do so, it tried to learn the concepts of extension in Brazil from the 1970s until the 2000s in contemporary times. This study considered the neoliberal social context of the University, dominated by educational policies focusing on the hegemony of liberal ideas about society, reflecting the great advances of capital on the organization of workers in the last decades and intensified in the 1990s. This research was guided by two great motivations: the opportunity to apprehend a way to enforce the commitment of public institutions of higher education to the disadvantaged sections of society and what role the university extension space plays as a socially committed public university. The general aim of this study is to identify inside the university extension education what does it mean for practitioners and extension activities and what results it produces to society and to the academic training of future professional citizens in the current neoliberal context. The research has been developed from an analytical and critical approach based on quantitative and qualitative data, using observation techniques and semi-structured interviews. We sought to investigate and understand the social reality, the main object of this work, with an interest in identifying the need for a new teaching/learning process and for a new university practice, in order to effectively improve an advanced academic formation. For this, some interviews have been conducted with teachers, students and the external community involved in extension actions in the period defined by the work, i.e., from 2008 to 2010. In this stage, it was observed that the academic work of university extension is essential to civic education. It was recognized too as a privileged space where university fulfills its social commitment towards society, as long as it joins scientific and popular knowledge having in view a new science and a new social order

Mulher como sujeito da criminalidade: um estudo sobre a realidade de presidiárias do complexo Penal Dr. João Chaves Natal/ RN

This work presents itself as a result of the research: Women as the subject of crime: a study on the complex reality of the criminal inmates Dr. John Keys - Natal / RN, done with women incarcerated in the Women's Pavilion Complex Criminal Dr. John Keys. Aimed to investigate the key determinants that lead women to enter the institution to be subject of crime. To better understand the object of our study, we start to understand and analyze the social reality, economic and cultural these women, as well as seizure of their family relationships and emotional, within a gender perspective and consider the analysis of major crimes committed and their determinations. In our study, it appears from successive approximations and procedures theoretical and methodological quality and quantity, we were privileged to documentary research, observation and semi-structured, beyond the theoretical foundation on the subject - that the question of increase in recent years, women in the criminal occurs as a result of socioeconomic reality experienced by those. At the same time, the study has also believe that poverty and crime are not phenomena of cause and effect, however, it is undeniable that the large number of prisoners (as) are poor and live situation of denial of rights. The main focus of the research points to the socio-emotional relationships, both marital and family as the main determinant for inclusion of women in crime, breaking with the myth that the woman is "fragile sex." And, more, points out that the woman in the process of emancipation and achievement of public spaces to commit a crime seek equal to the male. Moreover, the research also denounced in a prison system collapsed, and totally abandoned by the public. That denies all rights provided to prisoners (as), both inside and outside the "walls". It is a system that criminalizes and no one wants to fulfill its role, which is the functional rehabilitation and resocialization of (the) inmates (those). It is hoped that this work could contribute to the unveiling of the reality of women in the criminal - no pretension of exhausting it - and can also contribute to further studies on the subject

Entendendo as interações entre povos pesqueiros, manguezal e área protegida: RDS estadual Ponta do Tubarão (RN, Brasil)

The mangrove ecosystem has a great importance to maintaining marine biodiversity, and to the livelihoods of communities living around it. Despite its importance, many mangrove areas have been extensively cleared and converted to other uses. There are few places where communities can retain their traditional uses of mangrove. A good example of conservation of traditional costumes are the fishing communities of the Sustainable Development Reserve (Reserva de Desenvolvimento Sustentável RDS) Ponta do Tubarão. The creation of the reserve came from the own population, and the devastation of a mangrove area, which would be destined for activity shrimp, was one of the reasons that led the population to ask authorities the establishment of a legally protected area. Thus, this study aimed to investigate the environmental perception of the fishing communities of RDS Ponta do Tubarão with respect to the mangroves in a biological, ecological and social perspective as well as evaluate the influence of the reserve in the mangrove conservation and quality of life. To meet objectives of this study was required the appropriation of some method and approaches of ethnosciences and environmental perception. Data were collected through direct observation, and semi-structured interviews. Through content analysis found that the population has a strong dependence on the mangrove ecosystem, as well as provides a good ecological knowledge of ecosystem functions. It was also found that the reservation has a good performance in the conservation of the mangroves; however, need to outline strategies to conciliate both the biological and cultural conservation.

A produção de biodiesel no assentamento Canudos RN: perspectivas e limites da inclusão social

The need to become energy self-sufficient a country with which Brazil has sought renewable energy sources due to the possibility of depletion of oil in coming decades. This paper will examine the perspective of social inclusion the latest energy plan developed by the Federal Government: the National Program of Biodiesel Production and Use - PNPB. It aims to find out whether that work with family farmers who participated in the PNPB socially included and what limits its inclusion. Secondly, the objective is to analyze the Brazilian biodiesel production and its uses. The methodology used for the preparation of this study was to examine the literature, visits to the study area, conducting interviews with the leadership of the settlement, questionnaires and semi-structured interviews with families producing sunflower. Finally, the research dealt with the statistical data. After analyzing the data was verified that the instrument PNPB is able to promote the social inclusion of family farmers, but this occurred in the initial stages because the families involved need a minimum framework of organization and infrastructure to develop activities related to biodiesel

Redesenho das configurações estruturais na gestão universitária: ações derivadas da inovação e flexibilidade na legislação pós-LDB 1996

This paper is set in a scenario in which higher education institutions suffer from external pressure to increase efficiency. The legislation after the Law of Directives and Bases for Education (LDBE), from 1996, is characterized by the fragmentation in its implementation, raising a concern with flexibility and innovation in several normative devices as well as aspects that must be incorporated to its organizational structure. The policies examined in this thesis are: Distance Education (DE); Law of Innovation and the Program of Support to Restructuring and Expansion of Federal Universities (PSREFU). This thesis aims to observe to what extent the characteristics of innovation and flexibility, which mark the new post- LDBE educational legislation, influence the organizational redesign of the Federal University of Ceará (UFC). For being about implementation policies, using contingency approach in order to collect the internal dynamics permeating the redesign of higher education institutions, the thesis focuses on the impacts caused by flexibility and innovation. This is a qualitative research, with case study methods, archive research and semi-structured interviews with members of the university administration. The results don t allow us to confirm the adoption of a more flexible and innovative configuration in the university but it is possible to identify the presence of those elements in the implementation changes, characterizing the hybrid structure. The changes mainly expose the extension of the management of projects to the administrative and academic components related to the institution. In terms of projection, the study found changes in the elements which characterize the current setting and the tendency of the university for adopting a diverse organizational structure. However, if the decentralization of management persists, the academic units may adopt their own structural solutions, but with no evidence of changes in the professional organization in most units. In this perspective, this thesis states that there are difficulties when incorporating innovation and flexibility to their organizational structure, which lead to improvised solutions, superposing skills through the redundancy of structures created with the same purpose or copying exogenous solutions

Criação de empresas à luz do modelo de decisão effectuation: um estudo com mulheres empreendedoras no município de Currais Novos/RN

This study analysed the creation of businesses by entrepreneur women in the Currais Novos city, looking for verifying if they used making decision processes aligned to the Effectuation logic throughout the creation of their companies. To this, was accomplished a multiple cases and exploratory study, whit a qualitative approach of analyse, using the thematic life history technique that match accounts and semi-structured interview route, being accomplished like a long interview, where the researcher interact with the informer continuously. The semi-structured interview route was created by the adaptation of the interview route used by Tasic (2007). The present study appealed to a intentional selection of individuals in function of their importance in relation to the boarded theme. This means that the individuals were chosen in function of their social and theoretical representatively inside the considered situation. The participant individuals of this research were five entrepreneur women that act in the Currais Novos city, owners of five different companies. To the data treatment and analyse, was chosen the content analyse technique. This study worked with a priori theoretical categories. The categories of analyse in this study was obtained with base in the Effectuation approach (SARASVATHY, 2001a, 2001b, 2008), that is an alternative model of making decision to the classic model based in the causality principle. These categories are Clarity of Initial Aims , Tolerance to the Lost and Initials Investments , Control of Resources ( who I am , what I know and who I know ) and Promoting Over Contingencies . As result, the entrepreneur women researched, in a general way, hadn t clear initial aims at the companies creation moment, hadn t aversion to the risk to lose the time and the money that they were investing in the company in formation, they highlighted the products and services identity that offered with a strong link with Seridó region, they had experience in the field of activity in which they decided to open their companies, had the commitment of partners in the beginning of the business and they knew to transform the initial difficulties in opportunities. By the end, this study conclude that the entrepreneur women studied used, in a big part, making decision processes aligned to the Effectuation logic throughout the creation of their companies

Turismo, território e políticas públicas: uma análise do destino João Pessoa/PB

This study presents an approach to tourism activity from the perspective of the territory, analyzing the importance of the roles of the State and public policies for tourism development. Tourism in the northeastern region of Brazil begins to take its rise from the late 1970 through public policies, whose goal was to provide the necessary conditions for tourism development. The tourism public policies were the key elements in the production process of tourist territories in the region. In the state of Paraíba, the public authorities elected the coastline as the main attraction and the state capital, João Pessoa, as the locus for the tourism development, with the city receiving a series of public policies. In this context, this research aims to analyze the development process of three specific public policies for tourism development in João Pessoa: The (mega)Projeto Costa do Sol (1988), the PRODETUR/PB I and II (1997 e 2005) and the Plano Estratégico de Desenvolvimento do Turismo na Paraíba, the Plano Amanhecer (2000). This study was guided by the question that even having been contemplated by the tourism public policies, João Pessoa still remains in a peripheral position in the regional tourism market. The methodological procedures for this study were literature and documents research and semi-structured interviews with tourism public officials and representatives from local tourism trade. The research came to prove that the discontinuity between governmental administrations hampered the implementation process of the tourism public policies studied. It was observed that the implementation of tourism public policies in the long term depends on the interaction between governments, as well as the collective political will to develop tourism in Joao Pessoa
